Hello everyone! I got a question today for you, I got this Core i5-2300 which works perfectly fine so far, 40 minutes in prime95 and 0 problems, someone even been using this PC for 4h to play flash games, I tested Minecraft on it, and was doing stuff on it (mostly watching flash stream on twitch and browsing internet), and so far it works as intended, but I am about to do full stress test for at least couple hours.

But this CPU has one missing chip from bellow, I think it's missing because I looked onto pictures in Google images, I am not sure if this is normal or not (by that I mean if there wasn't suppose to be a chip there). I found a picture on Google that those microchips bellow cpu should look like this: http://imageshack.us/a/img20/9540/rtq7.jpg

The microchip that is missing is in this row: http://imageshack.us/a/img31/1082/x9h0.png

and it is around here somwhere in the center: http://imageshack.us/a/img707/4153/px8e.png

I would like to ask you What does that microchips does (the ones marked where the one is missing, I am asking about that full row), and if something can happen if I'll be using this CPU like that? It appears to be working 100% fine and If it passes my stress tests I will consider it as 100% functional even with broken chip. But I would like to know what this row of chips does and why the one there is missing if this impact something or not etc. My main curious question is, What this row of microchips does and how exactly they are called, then what impact can have that missing one when system is 100% functional and stable etc.

PS: Only this one single microchip is absent.

What do you speak of? because I don't understand. Btw I forgot to add to the first post that suppose previous owner doesn't know anything about broken chip there and he was using the cpu for half a year without issues (that is if we can trust him).

Anyway please explain to me what you just wrote.

Hmm, I see, i need to Google exactly what is resistor and what does it do to get my knowledge. Btw, is it possible if Intel changed something, the slot is empty for the Resistor but the soldering is still there? basically the place looks like this:

[]-[]

Where " [] " is solder and " - " is empty space, which is that green plate that the CPU has been build upon, you can see it in that empty space, between solders
 

That is how it looks like. The resistors may only be needed for a different model, but Intel uses the same case for them all. http://en.wikipedia.org/wiki/Resistor

I see, so I shouldn't worry about it and just use the CPU since it's working and all? and about working, I just finished 2h and 39min test - In place large FFTs.

All tests passed so I think that the system/CPU is stable. What do you think?

Would it be possible for a missing resistor to cause stutter or lag in some games (even when there is High FPS)? Because I have some issues with Minecraft, Terraria is running a little bit slower as well and I am thinking if this might be because of that resistor or not... Other games work just fine, everything else works fine as well. I have very high fps in minecraft but there is this stutter and sometimes game lags as well.
